Description
Technical field
The present invention relates to sturgeon cultivation technical field, and in particular to a kind of sturgeon hatching method.
Background technology
Sturgeon refers to the fish of Gadiformes, and sturgeon is under the jurisdiction of Osteichthyes, Actinopterygii, hard shell catalogue, Gadiformes.Sturgeon
It is one of earliest vertebrate of existing origin, because region or kind difference have mandarin sturgeon, Chinese sturgeon, sturgeon, bitter cured sub-, Zhan again
Etc. title, body weight:68-250 kilograms.China is that sturgeon kind is most in the world, is distributed most wide, resource country the abundantest
One.In China, domestic wild sturgeon has 8 kinds, they be distributed in Heilungkiang, Song Hua River, the acipenser schrencki of Wusuli river valley,
Huso huso and Karafuto sturgeon；It is distributed in the Changjiang river, the mandarin sturgeon of Drainage Area of Jinsha River, acipenser dabryanus and paddlefish；It is distributed in Yining etc.
Naked abdomen sturgeon in ground waters；It is distributed in Xinjiang Eerqisihe River, Boulogne support sea, the siberia platform of Bosten.Wherein, China
Sturgeon is the precious fish of special product of China, belongs to China national first class of protection animal.Sturgeon has preferable QI invigorating qi-restoratives, promoting blood circulation is treating stranguria
And the effects such as benefit stomach, and its is delicious soft and smooth, entrance is fragrant and sweet, and exactly sturgeon has many advantages, such as these, propagates sturgeon artificially
Gradually rise, propagate sturgeon artificially, constantly meet demand of the people to sturgeon.Also can be eaten just because of sturgeon body parts
With and delicious flavour is unique, therefore sturgeon breeding is obtained in that benefit higher.Propagate artificially sturgeon mainly prelarva, postlarva,
Juvenile fish is cultivated, i.e., juvenile fish cultivation mainly is turned into adult fish, so that people are edible.And in terms of sturgeon breeding hatching, cultivating then phase
To less, breeding hatching that this is mainly sturgeon is high to cultural technique requirement, is that sturgeon subsequently cultivates to accelerate sturgeon cultivation
Fry is originated, and improves cultivation efficiency, and sturgeon hatching technique also gradually increases, and current sturgeon hatching method is mainly puts embryonated egg
Put and hatched in the incubator with agitating function, water temperature needed for being kept during hatching, set brooding time.Although this hatching
Mode, improves incubation rate to a certain extent, has promoted the aquaculture of sturgeon, but due to needing to stir incubator back and forth,
Often occur stirring action it is excessive when, cause embryonated egg to destroy on the contrary, influence hatching, incubation rate does not reach ideal effect so that
Sturgeon cultivation cost increases.In addition, hatching when temperature be not bound with sturgeon hatching feature be adjusted water temperature current so that fertilization
Ovum cannot obtain the element such as required environment and oxygen material so that incubation rate is low, carry out increasing sturgeon hatching cost.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of sturgeon oosperm environment that rationally provides with oxygen material element,
And then improve the sturgeon hatching method of sturgeon incubation rate.
A kind of sturgeon hatching method, comprises the following steps：（1）Address choice：Near the free of contamination brook flowing water in mountain area
Pond is built, stream flows through through pond, stream has miniflow, wind sheltering, in the shade, and the pond depth of water is 5~6 meters, is had abundant water resources；（2）If
Put incubation net cage：It is incubation tank using net cage, mesh is set in net cage internal layer, screen cloth is soft, and outer layer net cage shields, will
The net cage for setting is fixed on the pure and fresh top layer of one jiao of pond water quality；（3）Fertilization：1~2 kilogram of use seminal fluid 12 of sturgeon ovum~
18 milliliters, seminal fluid is first diluted 180 times with sterilized water, be subsequently poured into fish-egg, uniform stirring 5~6 minutes makes smart ovum fully receive
Essence, stands a moment, discards sewage, and unsticking, 30~45 minutes unsticking time are carried out using talcum powder；（4）First stage hatches：Will
The good embryonated egg of unsticking is placed in incubation net cage is hatched, and hatching water temperature is 12~18 degrees Celsius, brooding time 18~24
Hour, Dissolved Oxygen in Water value is maintained at 4~5 mg/litres, keeps the meter per second of water velocity 0.8~1；（5）Second stage is hatched：Adjust
Whole hatching water temperature is 20~22 degrees Celsius, continues brooding time 68~72 hours, Dissolved Oxygen in Water value be maintained at 6~8 milligrams/
Rise, keep the meter per second of water velocity 1~1.2；（6）Phase III hatches：Adjustment hatching water temperature is 16~18 degrees Celsius, continues to incubate
24~48 hours change time, Dissolved Oxygen in Water value is maintained at 5~6 mg/litres, keeps the meter per second of water velocity 1.2~1.5；（7）
Membrane is managed：Continue to be cultivated 72 to 96 hours in incubator after juvenile fish membrane, water temperature remains 20~22 degrees Celsius, keeps water
The meter per second of flow velocity degree 1.2~1.5.
Further, the step of sturgeon hatching method（4）First stage hatches：The good embryonated egg of unsticking is placed on hatching
Hatched in net cage, hatching water temperature is 18 degrees Celsius, and Dissolved Oxygen in Water value is maintained at 5 mg/litres.
Further, the step of sturgeon hatching method（5）Second stage is hatched：Adjustment hatching water temperature is 22 degrees Celsius, water
Body dissolved oxygen value is maintained at 8 mg/litres.
Further, the step of sturgeon hatching method（6）Phase III hatches：Adjustment hatching water temperature is 18 degrees Celsius, water
Body dissolved oxygen value is maintained at 6 mg/litres.
By having the beneficial effect that the technological means present invention is obtained, the sturgeon hatching method is special according to sturgeon growth and breeding
Point, precisely adjusts environmental condition needed for sturgeon oosperm, there is provided its requisite oxygen material element, has preferably ensured the hatching of sturgeon,
Improve sturgeon incubation rate, it is strong to hatch the sturgeon fry constitution come, the follow-up cultivation of effective guarantee, reduce sturgeon cultivation into
This, improves sturgeon cultivation efficiency.And the method step is simple, easy to operate, it is adapted to popularization and application.
